b ackground: in 1991, wright described a superior oblique expander procedure for browns syndrome and superior overaction with good results. originally, this procedure has been performed with silicone band expander. the aim of this study was to report the results of treatment of a series of patients with a-pattern strabismus associated with overacting superior oblique muscle using the fascia lat...

To evaluate the long-term surgical outcomes of inferior oblique muscle recession (IO Rec) for the treatment of superior oblique palsy (SOP). We retrospectively studied 18 consecutive patients who had undergone IO Rec for the treatment of SOP. A follow-up of at least five years after the operation was required to be included in the study. In results the preoperative vertical deviation was 10.6 ±...

AIM To investigate changes in fundus excyclotorsion after inferior oblique myectomy or myotomy. METHODS The records of 21 patients undergoing strabismus surgery by a single surgeon between 2009 and 2012 were examined. Only patients who had undergone an inferior oblique myectomy or myotomy, with or without horizontal rectus muscle surgery, were evaluated. Digital fundus photographs were obtain...

PURPOSE Residual head tilt has been reported in patients with superior oblique muscle palsy (SOP) after surgery to weaken the inferior oblique (IO) muscle. The treatments for these patients have not received appropriate attention. In this study, we evaluated the superior rectus (SR) muscle recession as a surgical treatment. METHODS The medical records of 12 patients with SOP were retrospectiv...

PURPOSE The authors established a surgical treatment for excyclovertical strabismus in which either the inferior rectus muscle or the superior rectus muscle was transposed diagonally. The effects and the safety of the procedure, called skew transposition, were studied. METHODS Eighteen operations using local anesthesia with eye drops were performed on 17 cases, including 10 with superior obli...

To evaluate the long-term surgical outcomes of anterior transposition of the inferior oblique muscle (ATIO) in the treatment of vertical deviations resulting from superior oblique palsy (SOP). We retrospectively studied seven consecutive patients who had undergone ATIO for the treatment of SOP. A follow-up of at least five years after the operation was required to be included in the study. In r...

The paradigm that an "underacting" extraocular muscle is always atrophic or hypoplastic and that an overacting extraocular muscle should always be enlarged leads to inconsistencies with clinical observations. These include findings of "overacting" inferior oblique muscles, superior rectus muscle overaction or contracture syndrome, and normal extraocular muscle diameters in patients with apparen...
